Simply homemade Chinese style black bean sauce – made from fermented black beans (sometimes known as salted black beans).
The beans only need to be soaked briefly for 30-60 minutes, then they can be quickly made into a rich stir-fry umami sauce.

I love making pan sauces as they’re usually so easy—it takes little more than a squirt of different ingredients from multiple bottles, plus some garlic and ginger.
However, black bean sauce has always intrigued me as it contains something I had never used before. Black beans, of course.
Now we’re not talking canned or dried black beans here. Black bean sauce calls for fermented black beans, also called douchi. These are black soybeans that have been fermented and salted.
I have to admit that I really didn’t want to bother fermenting black beans (over 6 months) myself, but luckily you can buy them in packets, already fermented!
📋 Ingredients?

Most black bean sauce ingredients can be found at virtually any medium-sized grocery store. Only the beans may be a bit more difficult to find.
You should be able to pick them up at any Asian supermarket, or if you don’t have one nearby Amazon sells them too.
We just need 4 tablespoons fermented black beans to make a cup of black bean sauce (which should serve about 4 people), ie I would recommend getting the smaller packunless you want to make LOTS of black bean sauce.
- The red package (<--affiliate link) below is a 100g pack. I use about a third of this pack to make a jar of black bean sauce.
- The white pack (<--affiliate link) is 500g! I bought a large pack because I knew I would be doing a lot of testing.
Luckily they last forever. An opened pack should be kept in a sealed container in the refrigerator. They could easily last a year there.

- First we will Soak the fermented black beans in cold water for about an hour. After this time, drain and rinse the beans. The beans are very salty, so rinse well.
- Crush the beans Stir up a little with the back of a fork. Leave about a quarter of the beans whole, the rest can be mashed into a lumpy paste.
- Fry the garlic and ginger in oil with the black beans. Then add rice wine, soy sauce, rice vinegar, sugar, pepper and broth.
- Simmer together for about 5 minutes. Thicken the sauce with some cornstarch, then turn off the heat and it’s ready to use.
👩🍳PRO TIP The gravy will be a little salty, but once you’ve seared it with the meat and veggies, it’ll be tasty perfectly balanced. You can use a reduced-sodium broth if you’re concerned it may be too salty for your liking.
